52Magnonics — is an emerging field of modern magnetism, which can be considered a sub field of modern solid state physics.[1] Magnonics combines waves and magnetism, its main aim is to investigate the behaviour of spin waves in nano structure elements. In… …
53Nonlinear optics — (NLO) is the branch of optics that describes the behaviour of light in nonlinear media, that is, media in which the dielectric polarization P responds nonlinearly to the electric field E of the light. This nonlinearity is typically only observed… …

56Schwarzschild radius — The Schwarzschild radius (sometimes historically referred to as the gravitational radius) is a characteristic radius associated with every mass. It is the radius for a given mass where, if that mass could be compressed to fit within that radius,… …
57Pockels effect — The Pockels effect, or Pockels electro optic effect, produces birefringence in an optical medium induced by a constant or varying electric field. It is distinguished from the Kerr effect by the fact that the birefringence is proportional to the… …
58Micro black hole — MBH redirects here. For other uses see MBH (disambiguation) Micro black holes are tiny black holes, also called quantum mechanical black holes or mini black holes, for which quantum mechanical effects play an important role.[1] It is possible… …
59Metric tensor (general relativity) — This article is about metrics in general relativity. For a discussion of metrics in general, see metric tensor. Metric tensor of spacetime in general relativity written as a matrix. In general relativity, the metric tensor (or simply, the metric) …
60Self-focusing — is a non linear optical process induced by the change in refractive index of materials exposed to intense electromagnetic radiation. [Cumberbatch, E. Self focusing in Non linear optics , J. Inst. Maths Applics 6, 250 (1970)] Mourou, G. A. et al.… …
